Association Between Juvenile Psychotic Experiences and Problematic Gaming

Problematic gaming (PG) is an emerging mental health condition associated with significant adverse outcomes. Even though PG has been linked to other psychiatric disorders, its association with psychotic experiences (PEs) remains poorly explored to date. The aim of our study was to examine the association between both conditions in a large Brazilian community sample. We hypothesized that adolescents with PG were more likely to report PE compared with those without the disorder.

Our investigation was based on a cross-sectional subsample of a large Brazilian cohort (n = 1616; 13- to 21-year age range). Using the 7-item version of the Game Addiction Scale, participants were classified according to their gaming status: no PG, PG, or gaming addiction (GA). The association between PG, GA, and PE was assessed through linear regression analyses, which were adjusted for the presence of significant covariates, including other psychiatric conditions.

9.5% (n = 154) presented PG and 2.7% (n = 43) had GA. 28.0% received any Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis and the mean PE score was 9.39 (SD = 4.35). Participants presenting PG had greater levels of PE, compared with participants with no PG, even controlled by sociodemographic variables and the presence of any DSM-IV diagnosis (b = 0.96, 95% CI = 0.17-1.75, P = .017).

According to our results, PG was significantly associated with PE, even in the presence of other covariates. Although preliminary, these results suggest that PG and PE may have shared neurobiological and/or behavioral pathways.
